85 parts, built around the MAX3221CPW, ACS712ELCTR-30A-T-JSM, AZ1117CD and BAT42. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the SK21/AOG_AutoSteer repository on GitHub, at the commit this page was made from: the board is AutoSteer15-3/AS15.kicad_pcb and its schematic AutoSteer15-3/AS15.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask SK21 before reusing the design.
